Can I lose 3.3lbs / 1.5kgs in 6 days?

I need a challenge. I want to aim to lose 1.5 kilos before the end of the month. I have six days.
For the last 3 months I've been losing on average about a kilo, or just under a week. And that's without trying too hard. Just a bit of exercise, no alcohol and lots of good food.
Is it achievable? If I actually get off my *kitten* and work it for the next 6 days?

Would love some tips on how to go hard so I can see those results at the end of the week.
Thanks
Kim
